Overview

Tentative class to assist basic arithmetic operations between quantities without (like Numeric) and with (like UNumeric) units.

The fundamental problem here is that the desired unit conversion to convert the Numeric is different between additional methods (+,-) and multiplicative methods (*,/). In the former, the numeric should be converted to have the same units with the other operand, and in the latter, it should be non-dimensional.
